Consider an Erdman® Glass Lay-in System. Once the sealant has been laid on the rabbet, roller ball support rods raise to the level of the glass roll-in rollers. Your operator can then manually and ergonomically set the glass into the positioning area by gently gliding the glass over the glass roll-in rollers. Utilizing the roller ball support rods, the operator will then glide the glass over the table to rest against the positioning stops. The rods will then lower the glass part way into the frame above the sealant. Your operator can then insert your setting blocks as required, and then seat the glass.
